TRUNK-LOCK.

Specification of Letters Patent.

7 Patented Feb. 13, 191?.

Application filed September 23, 1916. Serial No. 121,737.

To all whom it may concern.

Be it known that I, Fnnonnrox J. Gimme, a citizen of the United States, and a resident of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Trunk-Locks, of which the following is a specification.

My invention relates to trunk locks, and more particularly to looks for wardrobe trunks, and belongs to that type of trunk locks in which a series of interlocking members on the interior of the trunk are locked together by turning the lock on the exterior of the trunk into its locking position.

By the present invention the interlocking mechanism on the interior of the trunk is greatly simplified and made more effective in operation, and the longitudinal shifting of the lock bar, which takes place upon rotation of the lock, is carried out in a very simple and effective manner, dispensing with the use of cogs, links and similar mechanical parts, the use of which is objectionable on the interior of a trunk.

Other objects of the invention will appear in connection with the following description and be pointed out in my claims, and with the foregoing and related objects in View, my invention consists in the features of construction, parts and combinations herein set forth and claimed;

In the accompanying drawing, forming a part of this specification and wherein the same reference numerals are applied todesignate the same parts throughout, Figure 1 is a fragmentary sectional view showing'the inside of a trunk with the parts in their locked position. Fig. 2 is a similar view with parts broken away and showing the parts in their unlocked position. Fig. 3 is a fragmentary sectional detail view showing the devices for operating the interior locking bar from the lock pivot, and Fig. 4 is a fragmentary perspective detail view of one pair of interlocking elements.

The sections of the trunk to be locked together are designated by the numerals 10 and 11,respectively. 'These parts may each be hinged or one may be hinged and the other stationary. On one of said sections, in the form shown on the part 10, are provided stationary locking members 12, here shown as flat plates, with projections 13 extending at the free ends thereof toward the interior of the trunk and rounded off at one end, as indicated at 14. Any number of these stationary locking members may be provided, three being illustrated in the drawing. The remaining one of the members 10 and 11, in the form shown that numbered 11, is provided with a sliding locking bar 15 mounted to slide in suitable ways on said part 11, the ways being provided, in the form shown, in clips 16 securedto the member 11 with the plates 17 beneath them in order to space the bar 15 a little distance from the member 11, and providing between them the guide apertures 18 in which the slide bar 15 is received and may move in an endwise direction. 111s bar 15 has notches 19 of a size to readily receive the locking members 12 and proj ections 13 and suitably spaced for that purpose, and adjacent to the notches 19 is provided with recesses 20 and locking projections 21 also preferably rounded at their ends, as indicated at 22. The parts described constitute the .means for locking the trunk sections together on the interior of the trunk, and it will be readily understood that when the trunk is closed, with the parts in the position shown in Fig. 2, the projecting ends of the members 12 enter the recesses 19 in the member 15, and when the latter is moved longitudinally in its guides, the upstanding projections 13 enter the recesses 20 in the bar 15 and the parts are retained in locked position by the coaction of the members 13 and 21, the holding thus effected being firm and secure and there being no tendency whatever of the parts to become disengaged from one another as they meet and hold on substantially straight engaging faces.

The means for efiecting endwise movement'of the locking bar 15 will now be described. The lock casing and its shank 241 are hinged together, as at 25, in the ordinary way. The shank 2 1 hasa preferably square hole 26 in which is received the pivot shaft 27, which is preferably riveted over so as to be firmly secured to the lock casing. The pivot. shaft 27 has a round portion 28 passing through and having a bearing in a suitable opening in the trunk lid 11, which, if desired, may be suitably reinforced at the point of hearing, as by a reinforcing plate 30. The rounded portion 28 of the shaft 27 extends through a slot 81 formed in a block or plate 33 on the interior of the trunk and to which the bar 15 is rigidly secured as by rivets 32. When this plate 32 is between the bar 15 and the trunk section 11, as in the form shown, the spacing plates 17, already referred to, 'are preferably placed between the said trunk section 11 and the bar 15 and are preferably of the same thickness as the plate 32, as are also the flat portions of the fixed locking members 12. This is a convenient and simple way to secure the proper relation of the coacting parts, but it will be understood that similar results may be secured in other ways. The rounded portion 28 of the pivot shaft 27 serves as an added guide for the movement of the bar 15 and plate 32, confining such movement to the straight, longitudinal reciprocation of the bar 15 and the attached plate 32. The means for actuating the bar 15 and attached plate 32 from the bar 28 comprise a cam piece or lever 34 and means thereon for imparting right line 1011 gitudinal movement to the bar 15 and plate 32 as the said cam piece or lever 34 is rotated by the shaft 27. In the form shown a square hole 35 is provided in said member 34, and the shaft 27 has its squared portion 36 passing through said hole and the parts held in place by a pin 37. This is a form of construction providing for ready assembly of the parts, but other means of connection whereby the member 34 is secured to the shaft 27 to rotate with the same may be resorted to. The means for imparting movement from the member 34 to the plate 32 comprise a slot or cam-way 38 which, in the form shown, extends across the member 32 at right angles to the slot 31, and a stud 39 projecting from the member 34 into said slot or cam-way 38. In the form shown the member 39 is substantially non rotatable with respect to the slot 38, being elongated and squared at its corners so as not to turn therein, and means are provided for the ready rotation thereof within the member 34. A ball bearing is preferably used to reduce friction and binding to a minimum, and in the form shown the stud 39 forms an integral part of a member 40. Said member 40 has a central positioning stud 41 and a half groove 42 for the bearing balls 43. It is received within an opening 44 in the member 34 which is grooved at 45 for the bearing balls, and the bearing is completed by the grooved face plate 4-6 which is preferably centrally positioned on the member 40 by means of the stud 41 and secured in place by any convenient means as by the screws 47.

The form of ball bearing is one which can.

be conveniently assembled and which is flat and prevents undue projection of any parts. Other forms of bearing may, of course, be utilized.

The operation of the apparatus will be readily understood from the foregoing. Before the trunk is closed the lock 23 is turned to the position shown in Fig. 2, the part 34 of the member 34 contacting with the part 15 of the bar 15 which provides a stop for the rotation of the lock, the lock being incapable of movement to the right beyond the position shown in Fig. 2, in which position the parts are in correct relation for permitting the lids to be opened or closed. With the lids closed in this position the lock 23 is rotated toward the left from the position shown in Fig. 2 until it occupies that shown in Fig. 1. When the portion 34 of the member 34 comes in contactwith the end 15 of the bar 15, as will be seen in Fig. 1, the endwise movement of the bar 15, resulting from the rotation of the lock, brings the projecting members 13 into the groove 20, and by the coaction of the members 13 and 21 the lids are held firmly looked through out their entire length. To disengage the interior locking devices it is only necessary to go through the reverse operation. The trunk, which has been locked with the usual lock by means of the key applied at the keyhole 23, is unlocked, the bolt is freed by turning the lock 23 outward on its pivot 25 and then the parts are brought to the position shown in Fig. 2, whereupon the interior locking members are disengaged and the lids of the trunk may be opened.

It is to be understood that the particular embodiment of my invention shown is for the purpose of illustration only and that I am not to be confined theretoeXcept as may be required by my claims, and that I may make changes therein and departures therefrom within the scope of my claims without departing from my invention or sacrificing any of the advantages thereof.

Having thus described my invention, I claim:

1. Means for locking two sections of a trunk together comprising fixed locking members on one section, a slidable locking member on the other section, a trunk lock, and a pivot shaft for said lock extending through one of the trunk sections, said pivot shaft serving as a longitudinal guide for the slidable locking member.

2. Means for locking two sections of a trunk together comprising a notched bar on one section and cooperating engaging members on the other section, a trunk look, a pivot shaft therefor, means whereby rotation of said shaft moves the bar endwise, and means whereby said shaft serves as a guide for the longitudinal movement of said bar.

In a device for holding two sections of a trunk together, a slidablelocking bar on one section, means adapted for engagement therewith on the other section, a look, a pivot shaft extending from 7 said lock through a section of the trunk, a plate secured to said locking bar and having a slot wherein the pivot shaft is received, said plate also having a cam slot, and a cam member rotating with said pivot shaft and adapted to enter said cam slot and to cause reciprocation of the locking bar upon rotation of the lock and its pivot shaft.

4. In a device for locking two sections of a trunk together, a longitudinally slidable locking bar, locking members adapted to coact therewith, a plate secured to said looking bar and having one slot therein substantially parallel to said locking bar and another slot at substantially right angles thereto, a lock for the trunk, a pivot shaft for said lock extending through a trunk sec tion and through the first named slot in said plate, a member on said shaft within the trunk and rotating therewith, a cam stud on said member extending into the second slot in said plate, and a ball bearing for mounting said cam stud in said member.

5. In a device for looking two sections of a trunk together, locking means on the interior of the trunk comprising a slidable member, a lock on the exterior of the trunk, a pivot shaft extending through the trunk, and means whereby upon rotation of said shaft said slidable locking member is reciprocated, said means including a member rotating with said shaft and a cam piece mounted thereon upon a ball bearing, and said cam piece having a non-rotatable connection with said slidable locking member.

6. In a device for locking two trunk sections together, fixed fastening members on one section, a cooperating locking bar slidably mounted on the other section, a plate to which said bar is secured at one end, a pivoted trunk lock, and means whereby rotation of the trunk lock imparts movement to said plate and bar, the end of the bar secured to the plate serving as a stop for the rotation of the trunk lock in each direction.

In testimony that I claim the foregoing, I have hereto set my hand, this 22nd day of September, 1916.
